Description

Technical Field

[0001] The invention relates to the technical field of automatic production line supporting equipment, in particular to a material receiving rack. Background Art

[0002] Profiles are objects with certain geometric shapes made of iron or steel and materials with certain strength and toughness through rolling, extrusion, casting and other processes. Such materials have certain appearance dimensions, certain cross-section shapes, and certain mechanical and physical properties. Profiles can be used alone or further processed into other manufactured products. They are often used in building structures and manufacturing and installation. Mechanical engineers can select the specific shape, material, heat treatment state, mechanical properties and other parameters of profiles according to design requirements, and then divide the profiles according to specific size and shape requirements, and then further process or heat treat them to achieve the design accuracy requirements. There are many types of steel profiles with complex specifications, and generally a multi-variety small batch production method is adopted. The demand for steel profiles is growing slowly, and it is difficult to continuously roll steel profiles with complex cross-sections, so the automation level of steel profile rolling mills lags behind other rolling mills. The layout of steel profile rolling mills includes horizontal, cross-country, chessboard, tandem, semi-continuous and continuous (see rolling mill). The layout of steel profile rolling mills is selected in different forms according to the product variety and production scale. Small and medium-sized rolling mills have applied continuous rolling technology with micro-tension or controlled loops. The advantages of this technology are large production capacity, good steel quality, ability to roll thin-walled products, high yield rate and automation, low production cost, and less manpower; but the equipment is complex and the investment is large. At present, the degree of automation in profile cold rolling processing is not high. Product collection and packaging are mainly completed manually, with high labor intensity and low efficiency. In addition, as labor costs increase year by year, it puts great pressure on the production and operation of enterprises; therefore, there is an urgent need to upgrade the profile cold forming industry. Existing processing equipment and processes need to be improved and transformed to automation, digitization, and intelligence, and ultimately realize intelligent manufacturing, liberate productivity, and improve efficiency.

[0023] Example

[0024] See also Figure 1-3The present invention provides the following technical solutions: a material receiving rack, comprising a slot frame 1, the sides of the slot frame 1 are respectively vertically fixed with a first column 2, a second column 3, a third column 4, a fourth column 5 and four guide columns 6, a lifting platform 7 is movably engaged between the four guide columns 6, a worm gear reduction box 8 is fixedly connected to the inner bottom wall of the slot frame 1, the input shaft of the worm gear reduction box 8 is connected to a lifting motor 9, the output shaft of the worm gear reduction box 8 is threadedly connected to a lifting screw 10, and the top support of the lifting screw 10 is connected to the bottom center of the lifting platform 7, A rotating reduction box 11 is fixedly installed on one side of the bottom wall of the trough frame 1, and the input shaft of the rotating reduction box 11 is fixedly connected to the rotating motor 12, and the output shaft at the top of the rotating reduction box 11 is vertically fixed to a rotating frame 13, and the top of the rotating frame 13 is fixedly connected to a cross arm 14, and the top of the middle part of the cross arm 14 is fixedly connected to a first cylinder 15, and the bottom side of the middle part of the cross arm 14 is movably connected to an upper pressure plate 16 through a guide rod, and the telescopic shaft of the first cylinder 15 is movably connected to the top surface of the upper pressure plate 16, and one side of the cross arm 14 is fixedly connected to a horizontal material shifting mechanism 17.

[0025] In this embodiment, the lifting motor 9 drives the lifting platform 7 to rise and fall along the four guide columns 6 through the worm gear reduction box 8 and the lifting screw 10, and the rotating motor 12 drives the cross arm 14 through the rotating reduction box 11 and the rotating frame 13, and the upper pressure plate 16 and the horizontal material moving mechanism 17 installed on the cross arm 14 are rotated ninety degrees so as to arrive at the set work station according to the packaging procedure, and then the components installed thereon cooperate with each other to achieve regular arrangement of the profiles.

[0026] Specifically, two parallel racks 18 are movably engaged on the outer sides of the first column 2 and the second column 3 through linear bearings, the top ends of the two racks 18 are fixedly connected to a cross arm 19, and a transmission motor 20 is fixedly connected to the side of one end of the groove frame 1. The output shaft of the transmission motor 20 is fixedly connected in series with two gears 22 through a linkage rod 21, and the two gears 22 are meshed with the corresponding racks 18.

[0027] In this embodiment, when the transmission motor 20 rotates, the two gears 22 mesh with the two racks 18, and the two racks 18 move up and down through linear bearings, while driving the cross arm 19 to move up and down, thereby lifting the material at the bottom or transmitting the material at the top to the bottom at a uniform speed.

[0028] Specifically, an adjusting screw 23 is horizontally threadedly connected to the middle of the outer side of the fourth column 5, a side pressure plate 24 is movably engaged with the middle of the inner side of the fourth column 5 through a guide rod, and the top end of the adjusting screw 23 is rotatably connected to the side pressure plate 24 through a bearing.

[0029] In this embodiment, by rotating the adjusting screw 23, the adjusting screw 23 pushes the side pressure plate 24 to move inside the groove frame 1, thereby shrinking the accommodating space of the groove frame 1 and adjusting the actual size of the packaging material bundle accordingly.

[0030] Specifically, the horizontal material moving mechanism 17 includes a horizontal guide rail 1701, a horizontal pneumatic material stopping shaft 1702 is movably engaged in the middle of the horizontal guide rail 1701, a horizontal material moving motor 1703 is fixedly installed at one end of the horizontal guide rail 1701, and the output shaft of the horizontal material moving motor 1703 is threadedly connected to the horizontal pneumatic material stopping shaft 1702 through a horizontal screw rod 1704, and a vertical pneumatic material stopping shaft 25 is fixedly installed on one side of the top end of the second column 3.

[0031] In this embodiment, when the horizontal material moving motor 1703 rotates, the horizontal pneumatic material blocking shaft 1702 is driven to move along the horizontal guide rail 1701 through the screw engagement of the horizontal screw rod 1704. At this time, if there is material on the top surface of the lifting platform 7, the horizontal pneumatic material blocking shaft 1702 will push the material to its set position, thereby realizing the orderly arrangement and straightening of the profile material. The vertical pneumatic material blocking shaft 25 is used for material blocking. When a large number of workpieces are loaded into the material trough, in order to prevent the workpieces from rolling out, the cylinder on the vertical pneumatic material blocking shaft 25 rises to prevent the workpieces from rolling out.

[0032] Specifically, the rotating frame 13 includes an outer sleeve 1301 , and the outer sleeve 1301 is screwed with an internal thread column 1302 .

[0033] In this embodiment, the outer sleeve 1301 is screwed together with the inner threaded column 1302, so that the overall length of the two can be adjusted, thereby adjusting the overall height of the rotating frame 13 to cope with packaging material bundles of different heights.

[0034] In this embodiment, the worm gear reducer 8 and the rotary reducer 11 are known technologies that have been disclosed and widely used in industrial production and daily life.

[0035] The working principle and use process of the present invention are as follows: when working, first, the rotating motor 12 drives the rotating frame 13 to rotate through the rotating reduction box 11, and then drives the upper pressing plate 16 and other mechanisms to rotate 90 degrees through the cross arm 14, so that the upper pressing plate 16 and other mechanisms leave the opening surface of the groove frame 1, and then the lifting motor 9 drives the lifting platform 7 to rise to the specified position through the lifting screw 10, specifically, it is preferably a workpiece height away from the upper end surface of the material rack;

[0036] When the two racks 18 are on the upper end surface, driven by the transmission motor 20, the workpiece passes through the cross arm 19 and follows the two racks 18 to descend to a workpiece height position on the upper end surface of the lifting platform 7 and stops. Then, the rotating motor 12 drives the upper pressing plate 16 and other mechanisms to rotate 90 degrees to reset through the rotating frame 13, and the first cylinder 15 pushes the upper pressing plate 16 to move down to the side of the workpiece;

[0037] Then, under the action of the horizontal material moving motor 1703, the horizontal screw rod 1704 rotates to drive the horizontal pneumatic material stopper shaft 1702 to move toward the workpiece, pushing the workpiece into the material trough, and then the cylinder of the horizontal pneumatic material stopper shaft 1702 pushes the stopper rod to reset, and the horizontal screw rod 1704 rotates in the opposite direction to drive the horizontal pneumatic material stopper shaft 1702 back to the initial position at one end of the horizontal guide rail 1701;

[0038] Then the rotating motor 12 drives the rotating frame 13 to rotate through the rotating reduction box 11, and then drives the upper pressing plate 16 and other mechanisms to rotate 90 degrees through the cross arm 14, so that the upper pressing plate 16 and other mechanisms leave the opening surface of the groove frame 1, ready for the next work, and the above actions are repeated;

[0039] When the workpieces fill the lifting platform 7, the lifting motor 9 drives the lifting platform 7 to move down a workpiece height through the worm gear reducer 8 and the lifting screw 10, leaving space for the workpieces to enter the material trough. When the workpieces fill another layer, the lifting platform moves down again until it reaches the predetermined position, and the workpieces are packaged;

[0040] When the workpieces reach a certain number and can be packaged, the upper pressing plate 16 moves downward under the action of the first cylinder 15, and the workpieces are compacted so as to be packaged.

[0041] On the left side of the material receiving rack, the side pressure plate 24 is moved by rotating the adjusting screw 23 to adjust the size of the material trough as needed.

[0042] At one end of the material receiving rack, a vertical pneumatic material stopper shaft 25 is used to stop the material. When more workpieces are loaded into the material trough, in order to prevent the workpieces from rolling out, the cylinder on the vertical pneumatic material stopper shaft 25 rises to stop the workpieces from rolling out. Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, for those skilled in the art, they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents.
